Free Spins
Unlock the path to victory with the (Skeleton) Key – when it radiates a green glow, it signals the entrance to a plethora of fantastic modifiers. Seek out the enigmatic red glowing key or perhaps even the elusive golden key...
Explore a mix of beloved modifiers and bonuses from the original game alongside brand-new bonus rounds like Skeleton Organ Free Spins and The Final Voyage Free Spins.
Activate the lucrative big money bonus, accessible through every feature in the game (you might even find it concealed behind the golden key)! Each of the Goonies offers a unique upgrade to aid you on your adventure.
Following any win of 15 times the bet or higher in the base game, players can either collect their winnings or opt to trade them for a chance to unlock one of the features – it could lead to Big Money or perhaps a Mystery Win!
As chaos ensues, your u-boat faces the looming threat of devastating damage. Can you navigate through the enemy's relentless assaults and secure the gold? Or will you succumb to the brutal realities of wartime at sea?
xBombs detonate, clearing the reel of non-winning symbols to make way for new ones, while also acting as Wilds. Additionally, xBombs boost the win multiplier by one before the subsequent reel collapse.
Activating three bonus symbols triggers eight Silent Hunter Spins, during which reel 3 expands to a height of 8 rows. Prepare for the torpedo launch sequence upon landing a winning combination alongside the Periscope Wild on reel 3. Successfully hitting the target causes the Periscope Wild to extend from the top to the bottom of the third reel, with each downward nudge providing a win multiplier. This feature also grants an increased win multiplier for the duration of the round. xBombs also bestow a sticky win multiplier for the remainder of the feature.
Four bonus symbols initiate eight Wolf Pack Spins. Load up the torpedo bay and gather xWays Wild symbols to assemble the torpedo. Launching a torpedo increases the win multiplier by one each time. Similar to other features, xBombs award a sticky win multiplier for the duration of the round.
